First Claim
Patent Images
1. A wireless handheld communication device, comprising:
- a keyboard having a plurality of buttons for inputting information into the device;
a graphical display;
a navigation tool by means of which a user interacts with the device, said navigation tool including a rolling element; and
a processor which controls operation of the device, said processor running a program which suspends operability of a subset of said buttons and which suspends operability of said navigation tool when a pre-selected action is taken by the user, said wireless handheld electronic device transmits data to, and receives data from a communication network utilizing radio frequency signals and wherein the data transmitted between said wireless handheld electronic device and the communication network supports voice and textual messaging.

Abstract
A handheld electronic device useful for wireless communication has a keyboard including a plurality of externally accessible keys. The keys can be disabled (i.e. the keyboard can be locked) to prevent accidental actuation thereof by using the navigation tool which has a depressible rolling member. Thus, for example, depression of the rolling member twice in succession or pressing and holding the rolling member down temporarily enables the keyboard lock. The lock can be disabled simply by depressing the rolling member and at least one other key.
